' AXLE-LUBRICATOR.

" Be it known that I, LLorn and {State of Virginia, have invented newand useful Improvements in Axle-Lubricw tors, of which the following isa specificat1on. A v

My invention relates'toimprovements 1n 'axlelubricators, and its primaryobject is the provision of a device of this character in the use ofwhich the spindle of a vehicle axle can be lubricated withoutremovingthe wheel therefrom, the invention comprehenda-lubricator which issimple, durable and, efliclent, and whlch may be manufactured and soldat acompa'ratively low cost.

With the above and other objects in view,

the invention :consists in the construction,

combination and arrangement of parts hereinafter fully described andclaimed, and illustrated n the accompanying drawing,

' wherein:

- Figure 1 isa sectional view taken on a. plane extending vertically andcentrally through a spindle equipped with a lubricator constructed inaccordance with m invention, theguard being shown in si e elevation.Fig. 2 is adetail perspective view of the means by which the cup of thelubricator is secured against loss. Fig. 3 is a detail per spective viewof'the cup of the lubricator.

'- Fig. 4 is a detail perspective view of the head of the lubricator,and Fig. 5 is a-detailperspective view of the wrench by means of whichthe cup may be applied or removed fromor 'turned upon the head.

Referring to the drawing by reference numerals, 1 designates avehicleaxle and 2 the spindle thereof. 3 designates the. hub, 4 the axlebox, and 5 the spokes of a wheel of the'usual form and construction, thewheel also comprising a hub cap 6. The wheel is secured in appliedposition by means of a nut 7 which is mounted upon the threadedextension 8 of. the spindle 2, and by means of a washer 9.

which is interposed between the nut and the adjacent epd of the hub. Thehub is recessed as at 10 to receive the nut 7 and washer 9 and also toreceive a portion of and to permit the operation of the lubricator.

The spindle 1s provided with a centrally located and longitudinallyextending channel 11 which communicates at. its outer end p ARLjoLm'atension 8 of .the spindle. citizen of the United 'States, residing atNorth Tazewell, in the county of Tazewell,

betwee'n'the channel .11 and the upper side 16 having its'edgescrew-threaded as at 17. The lubrlcator also comprises. a cylindricalcup 19.wh1ch is closed at one end and fully open at its other end. Theinner surface of Conununication the annular wall of the cup 19 isscrew-' threadedas at 20'. to permit the cup to be movably'mounted uponthe head 16; Ex

ed extension 1+1. The {extension 14 is threaded into the socket 13 tosecure the "lubricator in applied position. The .stud 15 hasia diametergreater than that of the ex-.

tension 8- of the spindle 2 whereby to\per-" mit it to act as a lock forthe. nut 7, that is to say, the stud 15 prevents the 'nut 7 fromaccidentally turning off of the extension 8 of the spindle 2. A passage18 extends through the head 16, the stud 15 andthe extension 14, wherebyto establishcommunication between the lubricator and the channel 11. Theouter closed end of the cup 19 is provided with an angular enlargement21, v

through the ducts 12. WVhen the lubricant which was forced upon theupper side of the spindle 2 by the initial turning of the cup 19 uponthehead 16 is exhausted, the spindle may be again lubricated by turnin thecup farther upon the head. It shoulc be thus apparent that the spindlemay be readily and quickly lubricated without removing the wheeltherefrom.,

lo prevent the cup 19'from being lost should it by accident becomedisplaced from the head 16, a guard 23 is secured to the inner side ofthe hub ca 6. The guard 23 comprises a circular body 23 and laterallyextending diametricallyopposed arms 23*.

The other arm23 of theguard. 23' is adapted to be engaged by I a spring catch;25.-which is secured to'the inner side.-of .tl:1 'hu-bcap 6. i The catch25- holds the'guard '23agaii1's't'inovement and it may, be readily andtn iclirl 'y; thrown out of nderstood tha h engagemerrtiwitlr the guard;when it is desired to movethe guardasidd o obtain ac cess to the cupWhile'I have'descri'he 'tli method of op eration oifthe 'invention,,-.together with the apparatusewhich'xl gnow -consider to-- bethe bestembodimentfthereof, I desire torhpve; it e apparatus shownis j merelyillustratme and that such 'changes may bem'ade wheif desired as are.within the sccipe, of the -claims'.z.
